As part of HPDI Technologies’ process for selecting suppliers we work with, we request that each supplier submit to us a completed Supplier Initial Evaluation form.

The online supplier initial evaluation form is broken into different sections to help us gain an understanding of your commercial operations, your technical expertise both in or outsourced, your testing & manufacturing capabilities, and your quality qualifications. It is important to us that this form be completed with as much detail as possible in order to understand how well your organization could meet Westport requirements.

You will notice that a number of the fields in this form are required and those missing information will be highlighted with a red asterisks as you try to move to the next step. If you have any questions or need assistance with completing this form, please contact HPDI Technologies Purchasing at
